When panning the canvas, there is stuttering/judder, and also the various frames/elements don't move together - they shift relative to each other. It's not great to look at currently.
I first observed this in early betas in September 2018 (under MacOS High Sierra), and the same is still present in 1.7.0.206 (now on MacOS Mojave).
